Isolation and characterization of a structurally unique β-hairpin venom peptide from the predatory ant Anochetus emarginatus

Most ant venoms consist predominantly of small linear peptides, although some contain disulfide-linked peptides as minor components. However, in striking contrast to other ant species, some Anochetus venoms are composed primarily of disulfide-rich peptides. In this study, we investigated the venom of the ant Anochetus emarginatus with the aim of exploring these novel disulfide-rich peptides.The venom peptidome was initially investigated using a...
